MACHINE FOR MAKING CELLULAR BISCUITS.

Specification bf Letters Patent Patented Aug. 26,1913.

Application filed August 19, Serial No. 449,208.

To all whom it may concern:

Be it known that I, soon H. PERKY, a citizen of the United States,' resident of Ithaca, in the county .of Tompkins and State of New York, have made a certain new and useful Invention in Machines for Making Cellular Biscuits; and I declare the following to be a full, clear, and exact description of the-same, such as will enable others skilled in the art to which it apper-v tains to make and use the invention, ref

erence being had to the accompanying drawings, and to letters or figures of reference marked thereon, which form a part of this specification. I

Figure l is asection of the machine, taken on the line l-,1 Fig. 4, with the parts thereof engaged. 2 is a side view with the parts separated. Fig. 3 is a plan view of the base of the machine with the forming plate shown in dotted lines. Fig. at is a section of the machine on the line 4-4 Fig. 3. Fig. 5 is a detail perspective view of one of the sections. Fig. 6 is a detail cross section of the discharging plate.

The invention relates to a form of food designed to be made of grain, and it conhave short vertical bearings s, at their large ends and taper each to a dull point or nearly so, and they have a chequered arrangement on the base, being not quite contigu ous to each other along diagonal lines, and having base intersp'aces or intervals d, slightly larger than their base diameter, 11 tervening, as shown in the draw ngs. This plate is designed to mold or form one face of the article. A similar molding or forming plate 6, also provided Withsimilarly arranged projections f, of similar form to those on plate a, is provided to form the other face of the article. While the projections f, have a chequered arrangement similar to that of the projections b, on plate a. their arrangement is such as to effect an alternation or interposition of the projections f, in the intervals between the pro ections 0. These molding or forming plates may conveniently be made in sections 8', secured 1na frame It, by means of suitable fastenmgs, such as the wedges indicated at 'w. Around each base of these two plates (a, and extends a shoulder g, which serves as a bearing for the side wall or inclosing p ece it, which is designed to inclose and give shape to the material in a circumferential manner. This inclosing wall may be made in one piece or in several pieces, and the breadth of its wall is determined by the altitude of a projection from its base, being a little greater than the distance between the bearings of the two plates and said altitude. This wall serves not. only to limit the circumferential boundary of the article, but also its thickness, and to that end operates as a stop to prevent the projections of one molding plate from coming in contact with the base of the opposite molding plate.

On the base of each forming plate rests a perforated discharging plate 2. This plate is comparatively thin, being equal to the depth of the bearings s, of the projections, and its perforations 7c,are of sufiicient size to allow its intermediate portions n, to rest squarely on the base when saidperforations engage the projections of the forming plate. These discharging plates areprovided with extensions p, projecting laterally and serving to engage the inclosing wall piece 72 In order to operate these plates the material in suflie cient-ly plastic condition is placed in proper quantity upon the ends of the projections of onei of these molding plates, which is engaged by the inclosing wall piece 72 Then the other molding plate is brought into forcible contact with the material, and is pressed into engaging position so that its shoulder g, bears against the margin of the wall piece. In the discharge of the formed article the perforated plates are kept in engagement with the inclosing wall it, and the molding plates withdrawn, then the perfo-.

rated plates are removed and the formed article can be taken from the wall piece It,

and removed to a pan for baking. As the shell form of this article is quite thin it can be-readily baked hard and crisp, and in this condition is designed to form an article of food which will bear transportation well and will form a desirable commodity for general distribution. IVhile-this article of food has superficially somewhat the appearance of a waffle, it is essentially diflerent in that the projections are not solid but are shell gave fine article character.
